[c-nsp] 837 and vbr-nrt size limitation

[Lobo]

We normally setup our DSL customers with an 837 and create a 
sub-interface off the ATM0 main interface.  We don't assign a vbr as we 
just leave it blank and let the DSLAM and ATM equipment take care of the 
shaping.  However, I wanted to apply a policy map and use LLQ on the 
connection outbound to our edge router.  To accomplish this I need to 
assing a vbr statement with hard coded PVC values so that the 
service-policy statement takes.  Upon trying to set this up I noticed 
that the router can only have a max of 800K as the size of the PVC.  
This represents a problem as our service is 7Mbps.  Is there any version 
of IOS that allows for a greater value to be entered or this some hard 
limitation on the router?  I tried 12.3(4)T11 non IP Plus.
